To solve the origin of the hard XRB, a long standing puzzle in X-ray astronomy, was one of the primary scientific goals to be addressed with ASCA.
From deep surveys, they resolved 35% and 80% the soft XRB into discrete sources.
They detected total 107 sources, with a flux limit of [10.sup.-13] erg [cm.sup.-2][s.sup.-1] in the 2-10 band, resolving 20-26% of the 2-10 keV XRB. (40) An important result is that they found evidence for the solution of the "spectral paradox" by detecting a significant fraction of sources with hard spectra.
Soon after the launch, Chandra resolved >75% of the hard XRB above 2 keV into discrete sources.
It is seen that a large fraction (~80%) of the XRB below 10 keV is now clearly resolved into faint, individual sources, mostly AGNs.
Pure cultures of the xylem residing bacteria (XRB) thus obtained were maintained at -80[degrees]C, as glycerol stocks for long term, and 4[degrees]C for temporary storage.
ARDRA was performed to determine the genetic diversity of the XRB in the collection.
One hundred and sixty-seven XRB were screened for inhibition of the BW pathogen.
Production of Volatile and Diffusible Antagonistic Substances by XRB
The XRB issued in September Accounting Standards Framework: A Multi Standards Approach and two consultation papers, including Accounting Standards Framework for General Purpose Financial Reporting by For-Profit Entities.
Large for-profit entities without public accountability would likely apply full NZ IFRS with reduced disclosures according to plans favored by the XRB.
Our tests use the same specification of excess bond and stock returns (XRB and XRS) used in Section IV.
